Glass relaxed at Naitanui criticism - The West Australian

West Coast captain Darren Glass says the club is happy with the output they're getting from Nic Naitanui but says he's not surprised at the recent deluge of criticism aimed at the 2012 All Australian ruckman.

Former players including Scott Lucas, Garry Lyon and Tony Shaw have been lining up to have a crack at the form of Naitanui in recent weeks, putting much of the Eagles' three-game losing streak on the 23-year-old's shoulders.

Glass admitted Naitanui was below his best in the Eagles' dramatic loss to Carlton at the weekend, but said he would expect the ruckman to bounce back when they play Fremantle in Sunday's western derby.

"I've played poor games - I didn't have a big impact in the last quarter against Port Adelaide, it happens," he said.

"I'm comfortable that Nic will respond.

"I haven't had a good look at his game from the weekend, but it's not always about kicks and stats and possessions and that sort of stuff.
